IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 160,755, dated March 16, 1875; application led December 16, 1874.

To all whom it may concern:

Be it known that I, WILLIAM DoYLE, of the city and county of Albany, State of New York, have invented certain new and useful Improvements in Base-Burning Parlor Cook- Stoves; and I do hereby declare that the following is a description thereof, reference being had to the accompanying drawings forming a part of this specification, in which- Figure l represents a sectional elevation of the stove, taken from front to rear. Fig. 2 is a sectional elevation taken from side to side. Fig. 3 is a lateral sectional elevation of the oven section of the stove, with the body of the stove in front of the oven. Fig. 4; is a plan view of the base-fines of the stove. Fig. 5 is a horizontal sectional view taken at line No. 1 in Fig. l. Fig. 6 is a horizontal sectional view taken at line No. 2 in Fig. 2. Fig. 7 is a horizontal sectional view taken at line No. 3 in Fig. l. Fig. 8 is a horizontal sectional view taken at line No. 4 in Fig. l. Fig. 9 is a horizontal sectional view taken at line No.5 in Fig. l.

My invention relates to that class of stoves known as parlor cook-stoves; and consists in the several devices, parts, and combinations hereinafter described, so arranged in their relation to each other as to render the stove proper capable at all times of having the draft reverted into its base for effective operation for warming purposes, and at the same time of conducting the hot gases about the oven, to heat the same, for cooking purposes, or for boiling, or both.

To enable others skilled in the art to make and use my invention, I will proceed to describe it in reference to the drawings in two sheets, and the letters of reference marked thereon, the same letters indicating like parts.

In the drawings, A represents the base section of the stove, inclosin g the side lues and return-nues Al A1. Bis the fire-pot section or wall inclosing the descending side ues leading into the base from the combustion chamber, the fire-pot, and ash-pan chamber. Gis the mica section inclosing the combustion-chamber and the lower portion of the fuel-reservoir. D is the top section inclosing the upper portion of the fuel-reservoir. E is the fuel-reservoir suspended over the fire-pot F, which re-pot is suspended or supported forward of a vertical central line of the fuelreservoir or eccentrically with the same, and is inclosed by the plates or casing a, (shown in Figs. l, 2, 5, and 6,) which plate or plates form the inner wall of the descending flues c c and the ascending flue d; In this invention I extend the base-plate orlower portion A3, comprising the lower portion of the stove, out laterally at its rear, as shown in Figs. l

and 4. Above the said extended portion A3 ably formed by a plate made in the form shown in Figs. l, 3, and 4, in which the bottom of the said plate is raised at adistance from the bottom plate of the base A3, so that the hot gases from the central return-flue A2 may circulate in part beneath, while the sides of the said plate extending up to the oven bottom form the division-plates for the separation of the iiues e and e. Placed in the ascending flue is a damper, dl, which when opened, as shown by full lines in Fig. 1, will permit the hot gases to ascend to the exit when the damper d2 is closed up, reverting the draft.

Made above the oven G, and between the said oven and the top plate H, is the iiuechamber J, which is divided into tlues f f, for the passage of the hot gases from the tlues c c into the said Hue-chamber and the returniluef, for the return of the hot gases toward the front, and into the ascending iiue d, as indicated by arrows in Fig. 6. The top plate H is provided with a pot-hole having a ringdamper, g, which ring-damper, when turned, as shown by full lines in Fig. 6, will permit the hot gases to enter the flue-chamber J from the side iiues c c through the side tlues ff, and circulate beneath the pot-hole, and escape thence through the return-luef to the ascending flue d,- b-ut when the said ringe Hermes damper is turned to position shown by dotted lines in Fig. 6, and by full lines in Fig. l, the hot gases will be prevented from having a passage to the ascending Hue in that direction.

At the rear of the oven is made a Hue, h, which leads from the Hue-chamber J into the rear of the base below the oven, as shown in Fig. l, and communicates with the central return oven-Hue c by the hooded Hue h1. A partial closing of the ring-damper will permit a degree of circulation ofthe hot gases beneath the pot-hole, and a passage to the ascending Hue, and at the saine time permit another portion of the hot gases to pass down the rear descending Hue h. When the damper cl2 is closed, as shown by full lines in Fig. 1, and the damper d1 is closed, as indicated by dotted lines in same figure, the hot gases will pass directly from the Hues c c, through the Hues f j', to the space beneath the pot-hole, and return direct to the ascending Hue d, through the Hue f', providedy the ring-damper is placed as shown by full lines in Fig. 6, when no other parts of the stove will be heated by the currents of hot gases with the other Hues, and the draft will be made nearly direct, as their circuit from the Hues cc to the exit will be short. When the damper d1 is opened, a portion of the hot gases will decend the Hues c c', and pass into the front side Hues A1 A1, and thence into the central return Hue A2, and thence back beneath the plates b b, Fig. 4, into the side Hues@ e beneath the oven to the rear of the same, and enter the central Hue c', and thence pass forward to the ascending Hue dto escape to their eXit. hile the hot gases entering the said side Hues o c thus pass to their exit, another portion of the hot gases entering the Hues c c will pass back and over the oven, through the Hues ff, and descend the rear oven Hue into the base, to be discharged through the hooded Hue into the central Hue e', and be carried by the draft of the other gases, and with the same, up the ascending Hue. When the ring-damper is open, andthe other dampers are permitted to be as last described, a portion of the hot gases will pass through the Hues in the base of the stove proper, and beneath the oven, While another portion will pass, beneath the pot-hole, thence to the ascending Hue. With a damper, h2, to close the rear oven-Hue h, shown by dotted lines in Fig. 1, all the hot gases will be reverted and made to circulate through the several base Hues, and beneath and front of the oven, when the damper ell is opened and the damper d2 is closed.

It is readily seen that, by these improvements, the oven may be heated for baking purposes at the same time the base of the stove proper is heated for warming purposes, by either passing all the hot gases in contact with the bottom plate and front plate of the said oven after their passage from the base Hues of the stove proper, or that the oven and a vessel set in the pot-hole may be hea-ted at the same time, and also at the same time the base of the stove proper is being heated 5 it is also further seen that, if desired, all the rear, front, top, and bottom plates of the oven may also be heated when the base of the stove proper is being heated; or, if desired, the hot gases may be made to circulate only beneath the pot-hole for the heating of any vessel set therein.

The advantages attending these improvements are obvious, and are, Hrst, aheating of a greater amount of surface for radiation of heat for warming a room; second, the oven may be heated for baking purposes at the same time the stove proper has its base heated for warming purposes; third, the oven and base of the stove proper may be heated for their purposes the same time the hot gases are made to circulate beneath a vessel that may be placed in the pot-hole; fourth, a vessel may be heated setting in the pot-hole without the oven or the base of the stove proper being heated, as may be desired in warm weather. These advantages give to the stove features which are not found in stoves of this class as heretofore made, and enable a housekeeper or other person to direct the hot gases to such parts as may be desired to be heated, and in greater or less volumes, as the purposes may require, whether in light or strong baking, or boiling, or warming.

It is to be understood that the curved plates b b, used bymein this stove, and also the ringdamper g, form in themselves no part of this' invention, as they belong to other inventions made by myself', for which Letters Patent hav e been granted, and are only used in this invention in combination with different parts not before used with them. In this invention the curved division-plates b b are used to stimulate the currents ot' hot gases passing from the central base-Hue to the side Hues in the base beneath the oven, whereas in their original place they were used to stimulate the current in the ascending Hues. also used in this invention is to effect a horizontal reverting of the currents of hot gases from the front of the fuel-chamber to the rear of the pot-hole, and thence back to the ascending Hue, which ascending Hue is on the same side of the said Hue-chamber at which the fire-pot is located, while in its original place and application the said ring-damper was used to direct the passage of the hotgases beneath or from the pot-holes as they passed through the top Hue from the combustion-chamber in front to the exit at the rear.

It is to be understood that I do not confine myself to any particular form of the Hues in the extended base A3, through which the hot gases pass from the Hues in the base of the stove proper, to heat the bottom plate of the oven on its lower side in their passage from the said Hues in the said base of the stove proper to the ascending Hue, provided' the Hues in the said extended base are arranged in such a manner that the hot gases from the base of the stove proper will pass beneath the bottom plate of the oven, and impinge in part upon the same, and pass thence to an ascending flue placed between the oven and the firepot. It is evident that the fines e e and e may be variously arranged for this purpose Without disturbing or interfering in any way with either the side ues or the return-flue in the base of the stove proper, or the ascending flue between the oven and the fre-pot, and that l any of the usual arrangement of ues heretofore used beneath ovens for the passage of the gases may be used, such as two horizontal sheet-fines, the lower leading from the iine A2 in the base of the stove proper tothe rear of the extended base A3, and an upper sheet-flue communicating from the said lower sheetlflue to the ascending ue in the front of the oven 5 or, again, the iiues may be formed by divisionplates set angularly in the said extended base, as indicated by vdot-ted lines w a" in Fig. 4, which would secure in the said base the necessary side and return ues or, again, two division-plates, z, Fig. 4, running parallel with each other, which will conduct the hot gases from the central ue A2, beneath the plates b, through side lnes outside the said strips, to be returned through the central space or tlue between; or, again, by a curved plate, so arranged as to form two fines, or for the passage of the gases to the rear of the base, and the other for their passage forward from thence to the ascending line. l

Any or all of the said modes of construction may be used as a part of the invention in lieu ot' the arrangement of fines shown.

It is to be understood that the rear flue h, in this invention, has no connection with the fines e or their equivalents, leading from the return-due A2 in the base ofthe stove proper, but only with the return-flue e, leading to the ascending flue d, and is to be used in connection with the other lines when it is desired to envelop the whole oven in a direction from over the top of the oven to beneath the same, through the return-ne e to the ascending line el.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination, with a heating-stove proper, of an oven, located laterally at the rear of said stove, and au ascending flue between the said stove proper and the said oven, and of the iine-chamber J, rear flue h, and returnflue e', to heat the said oven by the hot gases drawn from the combustion-chamber of the stove proper, and passing over the top, down the rear, and beneath the bottom, of the oven, and up the ascending ue, substantially as set forth.

2. In combination with a heating-stove proper and an oven placed laterally from the same, the iues e e and e', or. their described equivalents, leading from the tlues in the base of the stove proper to beneath the oven, and the flue-chamber J and rear ue h, leading from the combustion-chamber, to conduct one portion of the hot gases in a direction down into the base of the stove proper, and beneath the oven, to heat the same, and another portion over the top of the oven, down its rear, and beneath the oven, and among the hot gases led from the base-flues in the base of the stove proper into the ascending flue d, substantially as set forth.

3. The combination, with the side flues e e beneath the oven and the central return-flue A2 in the base of the stove proper, of the inclined plates b b, beneath which the hot gases may pass to the fines e e, substantially as and for the purpose set forth.

4. The combination, with the fines c c', leading from the combustion-chamber, and the ascending flue d, located adjacent to the said hues, of the flue-chamber J, provided with the side iiues ff and return-line f, and the damper d', to revert the draft beneath a pot-hole and direct the discharge of the hot gases to the exit-flue through the ascending flue, substantially as and for the purpose set forth.

5. rlhe combination, with the lues ff and return-flue f', of the ring-damper g, working in the flue-chamber J, located in the rear of the ascending tlne d and the hre-pot, substantially as and for the purposes set forth.
